Quoting A380US (Reply 1):The only real way is to through the states I did it through MIA.

Might be the most convenient becaue you don't have to switch airlines, but not the only real way. My bf, who lives in the UK, just did it on VS/CM, LGW-HAV-PTY and back; a little difficult going because VS was delayed but otherwise, very smooth. There are also several options through CCS, BOG and MEX.
